The answer is dialectical materialism. It’s not “my perspective.” These are objective laws of social development that were discovered by Marx, Engels, Lenin, and Italian bourgeois economists who discovered the existence of social classes with their own interests. Again, this is the development of materialist social thought, which has been going on for centuries. You with your meager knowledge cannot understand not only Capital, but even political economy for pre-schoolers. That makes your attempts to appear smarter than you are look pathetic.
